Tubing should follow contour of the cabinets.
☺
Cut tubing to desired length using square cuts
and proper cutting devise.
☺
Make no sharp bends.
☺
Keep tubing from the unit to the faucet as short
as practical for good flow.
Under sink installations following installation
diagram and the following procedures:
1. Connect tubing from faucet to meter.
2. Connect tubing from supply valve to unit.
Icemaker hookup (optional)
The drinking water device can be connected to any
standard refrigerator icemaker or icemaker / water
dispenser. (Do not connect to a commercial type
bar icemaker.)
To complete this operation, connect a tee with shut-
off valve into the faucet tubing and route tubing to
the refrigerator. (Hooking up to an existing copper
line is not recommended unless it is new
installation.) Shut off icemaker by lifting lever prior
to turning off the existing tap water supply line to
the refrigerator.
System start-up
Prior to start-up:
1. Check all connections be sure they are secure.
2. Turn on feed water valve and check for leaks.
(Turn off and correct leaks if leaks occur.)
3. Close faucet and wait five minutes to see if
leaks result.
4. If no leaks are present, turn metering valve
clockwise and set to 800 if AD2710C cartridge
is installed. Otherwise, set to gallons
recommended for your cartridge.
5. Open faucet and run water for approximately
ten minutes to condition filter cartridges. Initial
water may be slightly discolored or contain a
few small particles of filter media. These
particles are harmless and non-toxic. This is
normal during filter conditioning, and will
subside prior to the end of the 10 minute period.
Maintenance
Your drinking water system contains cartridges
which must be replaced periodically for proper
operation. (Please see page 2 for cartridge
information)
Note: Change-out procedures may be amended,
depending on source water conditions.
To change filter cartridges follow these procedures:
1. Close feed water valve by turning it clockwise.
2. Open faucet to release pressure.
3. Loosen and remove filter housings using
wrench provided and discard cartridges.
4. Wash the inside of the housings using mild
detergent and soft cloth. Thoroughly rinse all
soap before reassembly.
5. Replace filter cartridges.
John Guest® brand fittings
Model DWS-2S-2710-01 utilizes John Guest®
brand fittings. These user-friendly fittings provide
superior performance and virtually eliminate the
potential for leaks. Proper use of these
push-in
fittings is shown below. Along with these fittings, all
tubing selected must be of high quality and must be
cut with a plastic tube cutter or sharp razor with a
clean, square cut.
Should a leak occur at a fitting, the cause is
generally defective tubing. To fix a leak, relieve
pressure, release tubing, cut off at least 1/4" from
the end (square cut), reattach the tubing and
confirm the connection is leak free. Each time a
new connection is made, it is advisable to cut off
1/4" from the end of the tubing using these fittings.
